Higher-Order Topological Insulators via Momentum-Space Nonsymmorphic Symmetries
Jinbing Hu, Songlin Zhuang, Yi Yang
The topology of the Brillouin zone, foundational in topological physics, is always assumed to be a torus. We theoretically report the construction of Brillouin real projective plan…
Physical essence of propagable fractional-strength optical vortices in free space
Xiaoyu Weng, Yu Miao, Yang Li +3
Fractional-order vector vortex beams are recently demonstrated to be new carriers of fractional-strength optical vortices. However, why can those new vortex beams formed by the com…
Different Channels to Transmit Information in a Scattering Medium
Xuyu Zhang, Jingjing Gao, Yu Gan +6
A channel should be built to transmit information from one place to another. Imaging is 2 or higher dimensional information communication. Conventionally, an imaging channel compri…
Roles of scattered and ballistic photons in imaging through scattering media: a deep learning-based study
Xuyu Zhan, Jingjing Gao, Yu Gan +6
Scattering of light in complex media scrambles optical wavefronts and breaks the principles of conventional imaging methods. For decades, researchers have endeavored to conquer the…
Multiple-Photon Resonance Enabled Quantum Interference in Emission Spectroscopy of N_2^+
Xiang Zhang, Qi Lu, Yalei Zhu +13
Quantum interference occurs frequently in the interaction of laser radiation with materials, leading to a series of fascinating effects such as lasing without inversion, electromag…
Nonparaxiality-triggered Landau-Zener transition in topological photonic waveguides
An Xie, Shaodong Zhou, Kelei Xi +6
Photonic lattices have been widely used for simulating quantum physics, owing to the similar evolutions of paraxial waves and quantum particles. However, nonparaxial wave propagati…
Electric polarization and its quantization in one-dimensional non-Hermitian chains
Jinbing Hu, Carmine Antonio Perroni, Giulio De Filippis +3
We generalize the modern theory of electric polarization to the case of one-dimensional non-Hermitian systems with line-gapped spectrum. In these systems, the electronic position o…
Property unification of inherent amplitude, phase and polarization within a light beam
Xiaoyu Weng, Yu Miao, Guanxue Wang +6
Is it possible to modulate the inherent properties of a single light beam, namely amplitude, phase and polarization, simultaneously, by merely its phase? Here, we solve this scient…
Light beam carrying natural non-integer orbital angular momentum in free space
Xiaoyu Weng, Yu Miao, Guanxue Wang +5
Light beam with optical vortices can propagate in free space only with integer orbital angular momentum. Here, we invert this scientific consensus theoretically and experimentally…
THz Near-Field Imaging of Extreme Subwavelength Metal Structures
Xinzhong Chen, Xiao Liu, Xiangdong Guo +15
Modern scattering-type scanning near-field optical microscopy (s-SNOM) has become an indispensable tool in material research. However, as the s-SNOM technique marches into the far-…
Extraction of inherent polarization modes from a single light beam
Xiaoyu Weng, Yu Miao, Qingli Zhang +4
Superposition of two independent orthogonally polarized beams is a conventional principle of creating a new light beam. Here, we intend to achieve the inverse process, namely, extr…
Establishment of the fundamental phase-to-polarization link in classical optics
Xiaoyu Weng, Xiumin Gao, Guorong Sui +4
Vector polarization induced by a change in scalar phase has been far beyond our understanding of the relationship between polarization and phase in classical optics due to the enta…
Coherent control of superradiance from nitrogen ions pumped with femtosecond pulses
An Zhang, Qingqing Liang, Mingwei Lei +8
Singly ionized nitrogen molecules in ambient air pumped by near-infrared femtosecond laser give rise to superradiant emission. Here we demonstrate coherent control of this superrad…
Lasing without population inversion in air
André Mysyrowicz, Rostyslav Danylo, Pengji Ding +8
A cavity-free laser in the sky could lead to revolutionary improvements in optical remote sensing for atmospheric science. Abundant in air, nitrogen molecules are prime candidates…
Free-space creation of ultralong anti-diffracting light beam with multiple energy oscillations adjusted using optical pen
Xiaoyu Weng, Qiang Song, Xiaoming Li +4
A light beam propagating with an infinite anti-diffracting distance requires infinite power to preserve its shape. However, the fundamental barrier of finite power in free space ha…
